So Keith told me,

that he told his friend he is with me now.

Then his friend asked if I am strict?
So next time can he still go drinkingla-kopi with them(guess also 'coz she's a female).

I think next time if I see this friend of his, I will tell her,

"yah, actually I am quite strict. When Keith go out play woman, I INSIST he must use protection."
